To all whom it may concern:

Be it known that I, HORATIO G. GILLMoR,

'a citizen of the United States, residing at Bath, in the county of Sagadahoc, State of Mame, have invented certain new and useful Improvements in Rail-Joints, of which the following is a specification accompanied by drawmgs- This invention relates to rail joints and one of its ob'ects is to so form such joints as to eifectualiy su port the rail ends and overcome the tent ency to vertical movement of one rail end relative to the other as the wheels ass.

Another object is to increase the area of contact of the parts with the heads and bases of the rails; and to so combine the parts that the stresses will be so distributed among'the arts, under all conditions of loading the oint, that each part will take its portion of the working stresses.

Further objects of the invention will hereinafter appear; and, to these ends, the invention consists of a rail joint for carrying out the above objects, embodying the features of construction, combination of elements and arrangement of parts, having the general mode of operation as hereinafter described and claimed in this specification and shown in the accompanying drawings; in which:

' Figures 1 and 2 are, respectively, a section throu h the parts at'the plane X and a side e evation, partly in section, of a joint embodying the invention. tion of the parts, at the plane XX, showing their. relative positions before theparts are fully drawn together by the bolts. Figs. 4, 5 and 6 are sections illustrating modified forms of joints embodying the invention,

Similar letters refer to similar parts throughout the several figures.

A represents the meeting ends of the rails.

B re resents fish bars provided with flan es C to engage with the under side of the leads of the rails, and L to engage with the upper surfaces of the bases of the rails.

C represents side bars engaging with the flanges K and L of the fish bars.

E is a chair constructed with anupright F and a fin or flange I.

D represents bolts for drawing together the parts of the joint and securing them in position.

The upright F of the chair E is rovlded with ribs or serrations G and the si e bars C at the corresponding side of the joint are surfaces near the webs of the rails.

Fig. 3 is a sec-' provided with grooves or serrations H adapt ed to en age with the ribs or serrations on the upright F of the chair.

The bevel of the flanges K and L of the fish bars 3 is so arranged that, when the fish bars are in place before the parts are fully drawn into position the flange L will contact 7 over a large portion of its lower surface with the up er surfaces of the bases of the rails while t 1e flan e K will contact with the under surfaces of the heads of the rails, firs g at ne side bars C are given such a bevel that when the bolts are tightened and the side bars are drawn into position, the flanges K of the fish bars will be forced upwardly into intimate contact with the under surfaces of the heads of the rails. By constructing the fish bars C in this manner contact of the fish bar flanges with a large ortion of the under sur faces of the rail heac s isinsured' even though set up, and the movement of the side bar C toward the axial plane of the rails, its surface being in contact with the flange L of the fish bar, draws the chair E slightly vertically; so

that, when the bolts are fully set up, the base of the chair E is in contact with the bottom surfaces of the bases of the rails and at the same time the side bar 0 and the u right F in such firm contact with one anot er that they together with. the fish bar B are virtually one piece for resisting the stresses set up by the wheels as they pass over the joint.

In the drawings the ribs or serrations of the chair and the corresponding grooves or serrations. of the side bar are shown formed longitudinally upon the pieces. Theyrnight also be formed transversely upon both the chair and the side bar if desired. It will be understood also that the parts may be formed with plane surfaces of contact, instead of forming them as illustrated, the friction of the contactsurfaces and the shearing stresses upon the bolts transmitting stresses to the chair from the fish bars.

rail ends. it is desirable, therefore, that the area of the section of the parts of the joint.

resisting the stresses set up at this plane should be as great as possible. In the forms of rail joints ordinarily constructed the areas f the sections of the parts are approximately constant. To reduce the amount of material required. in forming the joint without reduction in its strength, the si .e bars 6, instead of being carried the whole length of the chair at each side of the axial plane of the rails, are formed as short bars overlapping the opening in the joint at eacu side of the axial plane for a sufficient distance to give the necessary strength. In the vicinity of the bolts, beyond the ends of the side bars, there are employed, to form the necessary connections between the fish bars and the chair, short blocks Q these blocks being formed with grooves or serrations similar in all respects to the grooves or serrations on the bars C. These blocks at one side of the joint are formed with an arm or flange M provided with one or more spiking apertures to receive the spikes.

The chair E is also provided with spiking apertures at both sides of the joint, those at one side being arranged to register with the spiln'ng apertures of the lugs M.

In the form of the joint illustrated in Fig. 4, instead of employing a single chair two chairs are employed each having uprights F with ribs or serrations G adapted to interlock with corresponding grooves or serrations H on the side-bars C as above described.

In Fig. 5 is indicated a modification of the form of joint illustrated in Fig. 4; in which,

instead of forming the fish bars and side bars separately as above described, they are combined in one bar B this being formed with grooves or serrations H to engage with corresponding ribs or serrations G in the uprights F of the chairs E.

In the form of the joint illustrated in Fig' 6, a chair similar to that illustrated and described in connection with Figs. 1 to 3, inclusive, is employed with a side bar 'B (such as illustrated in Fig. 5) at the side of'the rails upon which the upright of the chair is, and a fish bar B of the ordinary form is employed at the opposite side of the rails.
